assistant_chat.py and spec_creation.py imported is_valid_project_name
(returns bool) aliased as validate_project_name. When used as
`project_name = validate_project_name(project_name)`, the project name
was replaced with True, causing "Project not found in registry" errors.

All 5 WebSocket endpoints (expand, spec, assistant, terminal, project)
were closing the connection before calling accept() when validation
failed. Starlette converts pre-accept close into an HTTP 403, giving
clients no meaningful error information.
Server changes:
- Move websocket.accept() before all validation checks in every WS handler
- Send JSON error message before closing so clients get actionable errors
- Fix validate_project_name usage (raises HTTPException, not returns bool)
- ConnectionManager.connect() no longer calls accept() (caller's job)
Client changes:
- All 3 WS hooks (useWebSocket, useExpandChat, useSpecChat) skip
reconnection on 4xxx close codes (application errors won't self-resolve)
- Gate expand button, keyboard shortcut, and modal on hasSpec
- Add hasSpec to useEffect dependency array to prevent stale closure
- Update keyboard shortcuts help text for E key context
